Composite materials are made by impregnating a non-conductive material with a conducting monomer to form a monomer-impregnated non-conductive material, and polymerizing the monomer-impregnated non-conductive material to form the composite material. The composite materials are used in medical devices and implants.

Adhesion of conducting polymers on diverse insulating and conductive substrates via a hydrophilic adhesion layer, where one or more functional groups may be disposed between the substrate and the hydrophilic adhesion layer. Adhesion of the conducting polymers on the substrates is such that adhesion is maintained or substantially maintained in wet physiological environments.

The invention relates to a method for grafting an organic film onto an electically conductive or semiconductive surface by electro-reduction of a solution, wherein the solution comprises one diazonium salt and one monomer bearing at least one chain polymerizable functional group.
